another crazy thought

woke up after 3hr of sleep, cant sleep again.then had another crazy thought.
This is more for the guys..i wonder what guys will do in the situation i'm going to describe.

Let say, guy likes a girlA at place A.
Then guy left place A to B.
At place B, he knew a girlB who is similiar to girlA, so alike and with her own uniquness.And assume both girls like him. What will a guy normally do?

1. choose girlB as they are in the same place + so alike n maybe even better than girlA.
OR
2. choose to like girlA as he believes she is still the one.
OR
3. 2-time and find out who is the better one.
OR
4. 2-time and enjoy the fun.
OR
5. choose not to like any after that.
OR
6. do no action
OR
7. u have ur own tactic..then this u have to share with me.Hhehe. or there more other things guys will do. Do share with me as i find guys have interesting mind set which is so diff from girls.

ok can see how crazy i can be when i suffer from lack of sleep or jetlag.sigh..
k i'll try to sleep a few more hrs again. actually only 1 hr.
hv to go uni earlier today.
